[1]} studied the effect of AGN on two morphological parameters, asymmetry, and concentration. They used the same asymmetry parameter as defined in our work, finding an insignificant difference between asymmetries of active and non-active galaxies. However, in their concentration index, defined similarly to CCON, but using \(r_{90}\)  instead of \(r_{80}\) , the authors found much larger values of the concentration index when an AGN is present, that is in line with our findings and Fig. REF . The most similar work to ours is that by [2]}, where they used a sample of \(\sim \)  600 non-active galaxies from the AEGIS survey [3]} at 0.2 \(<\)  z \(<\)  0.6, and analysed the effect of an AGN on four morphological parameters: Gini, asymmetry, Concelice concentration index, and M20 moment of light. They concluded that AGN contributions above 20% have an impact on most of the morphology measurements that depend on the morphological characteristics of the original galaxies. In comparison to [2]}, we provide a more detailed analysis, considering a larger sample of testing non-active galaxies, with precise known visual morphologies, testing five different AGN contributions, and adding two more parameters (CABR and SMOOTH) that were not analysed previously, and that very often are used simultaneously with other parameters in the morphological classification of galaxies [5]}, [6]}, [7]}, [8]}, [9]}, [10]}
